District Court Judge Mark Warner told 25-year-old Emanuel Doll in court Tuesday that if convicted of first-degree murder after deliberation and first-degree murder of a child by a person in a position of trust, he could go to prison for the rest of his life.

He also potentially faces the death penalty.

Doll is accused of killing his twin sister’s son with an ax at their father’s Broomfield home on Thursday.

Doll’s preliminary hearing was set for July 14.

Warner anticipates unsealing the public documents in the case that might reveal what happened inside the home.
